[Wine]How to help improving Wine?

[Walt Ogburn]

Hi Emanuele,

If you want to try to track down the source of the problem and fix it, you
will probably have to compile Wine from source instead of using the Debian
package, and see what happens when you make small changes.

I took a look at ALOHA, and saw the same error as you did.  This comes
from an ERR command in dlls/kernel/syslevel.c.  That means that Wine
thought something was wrong and halted, as opposed to some crashes where
the program crashes hard.  If you type "cont" (continue) into the debugger
a few times, you will end up with a more-or-less OK-looking plot, as far
as I can tell.  If you want to work on debugging, that function and the
others mentioned in the backtrace are the place to start:
